Hawk 2XL Product Manual, Rev. B 5
3.0 General description
The drives are a member of a family of low cost, high performance, highly reliable, random access storage
devices designed to meet the needs of the OEM marketplace.
The drive records and recovers data on 3.5 inch (89 mm) fixed discs.
The drive supports the Small Computer System Interface as described in the ANSI SCSI-2 and SCSI-3 Inter-
face Manuals to the extent described in this product Manual (Vol. 1), which defines the product performance
characteristics of the Hawk 2XL Family of drives, and the SCSI Interface Product Manual P/N 77738479
(Vol. 2, Version 2) which describes the general interface characteristics of this and other families of Seagate
3.5-inch drives.
The drive interface supports multiple initiators, disconnect/reconnect, self-configuring host software and auto-
matic features that relieve the host from the necessity of knowing the physical characteristics of the targets
(logical block addressing is used).
TheHead/Disc Assembly (HDA) is environmentally sealed at the factory. Air recirculates within the Head/Disc
(HDA) through a nonreplaceable filter to maintain a contamination free head/disc environment.
Refer to Figure 2, an exploded view of the drive. NEVER disassemble the Head/Disc Assembly (HDA). This
exploded view is for information only. Do not attempt to service items in the sealed environmental enclosure
(heads, media, actuator, etc.) as this requires special facilities. The drive contains no parts replaceable by the
user. The drive warranty is voided if the HDA is opened.
The Hawk 2XL Family drives use a dedicated landing zone at the innermost radius of the media to eliminate
the possibility of destroying or degrading data by landing in the data zone. The drive automatically goes to the
landing zone when the power is removed.
The Hawk 2XL Family drives incorporate an automatic shipping lock which prevents potential damage to the
heads and discs that result from movement during shipping and handling. The shipping lock is automatically
disengaged when power is applied to the drive and the head load process begins.
The Hawk 2XL Family drives decode track location from the servo data embedded on each surface to elimi-
nate mechanical transducer adjustments and related reliability concerns.
The Hawk 2XL Family drives use a high performance actuator assembly that consists of a low inertia, bal-
anced, patented, straight arm design that provides excellent performance with minimum power dissipation.
